magneto-optic effect in which the electric flux density vector of a linearly polarized electromagnetic wave is rotated about the direction of propagation as it passes through a gyromagnetic medium subjected to a magnetostatic field having a component of magnetic field strength along the direction of propagation

Note – The Faraday effect is due to a birefringence where the refractive index is different for two waves circularly polarized in opposite senses. The angle of rotation is proportional to the magnitude of the magnetic field strength and to the distance travelled in the medium. The coefficient of proportionality is called the Verdet constant.
